Comparison of the CAD 3D model and laser augmented 3D measuring device

U ovom završnom radu opisani su koordinatni mjerni uređaji za mjerenja u proizvodnji, napravljena je osnovna podjela koordinatnih mjernih uređaja, opisana njihova izvedba i primjena. U poseban tip koordinatnih mjernih uređaja spadaju 3D mjerne ruke koje se u današnje vrijeme sve više koriste u svim fazama proizvodnje. Za potrebe završnog rada odrađeno je mjerenje u Metalskoj industriji Varaždin. Mjerenje je izvršeno uz pomoć 3D mjerne ruke s laserom, skeniran je eliptični zasun DN150 PN16. Rezultati mjerenja uspoređeni su s CAD modelom u svrhu dobivanja odstupanja stvarnog komada i modela.In this final paper are coordinated measuring devices for measurements in production described, the basic classification of coordinated measuring devices is made, their design and applications are described. A special type of coordinated measuring devices includes 3D measuring hands which are nowadays increasingly used in all phases of production. For the needs of this final paper, the measurement was performed in the Metal Industry Varaždin. The measurement was performed using a 3D measuring arm with a laser, an elliptical latch DN150 PN16 was scanned. The measurement results were compared with the CAD model for the purpose of obtaining the deviation of the actual piece and the model
